It's pretty good, except my experience is that __parameters works only in
the narrow case of a verbatim forward. I rarely find I need to implement a
verbatim forward; I almost always seem to encounter a forwarding pattern
when it is necessary to perform a parameter transformation of some kind, or
a parameter injection. You need to be able to handle the arguments and
iterate/manipulate them.
I find I'm typically synthesising wrappers or shim's, not verbatim
forwarding... which isn't strictly the topic of this thread, but it's a
100% related problem, and it seems to be what I actually need to do 95% of
the time rather than the challenge in the OP.
